Installation instructions

l Remove the front insulation shell (12).
Keep the SOKI secured to the rear
insulation shell (2).
l Mark the holes to be drilled through the
insulation and drill with an 8 mm bit.
l Secure the SOKI to the wall with the fixing
screws (S6 x 60 mm) and Rawl plugs (S8)
supplied. For this, use a suitable Phillips
screwdriver.
l Join the solar station and the cylinder or the
collectors with suitable pipework.
All fittings are tightened at the factory,
making re-tightening generally unnecessary.
Nevertheless, check the system for leaks during
commissioning (pressure test).
2.2
Cylinder installation
C
With the SAS SOKI cylinder connection set
(order separately 22 04 63), the SOKI can be
installed on the SBB ... plus cylinder itself.
The 1" twin nipple (13) of the SAS SOKI for flow
and return are sealed into the connections of
the indirect solar coil of the cylinder.
The flow line of the SAS SOKI (thermometer,
gravity brake) is secured with a union nut.
To secure the return line to the SOKI, initially
remove the flow meter (8) from the SOKI. Then
join the flow meter (8) and the fill & drain
valve (5) of the SAS. Finally, refit the flow
meter (8) to the pump assembly. Then secure
the SOKI (with fitted fill & drain valve) with the
union nut (1") to the 1" twin nipple (14) sealed
into the cylinder.

The SOKI is installed into the return line (cold
side, process medium flows towards the
15
collector) of the solar circuit. In addition, fit
the thermometer supplied, together with the
sensor sleeve, into the flow line (hot side,
process medium flows from the collector).
Observe the solar panel operating and
installation instructions, as well as the DVGW
Code of Practice GW 2 [or local regulations].
Use solder to DIN EN 1004: CP105 and CP203;
17
both are used without flux. Only solder
gunmetal and brass fittings with flux F-SH-1
to DIN 8511. Other flux could compromise
the corrosion resistance. Seal lines made
with locking ring fittings, press fittings and
18
corrugated hoses with suitable sealants. Seals
must be resistant to glycol and temperatures
up to 180 °C. Use reducers on site to join the
lines to pipework with alternative diameters.
